Do I Know This Already Quiz

The purpose of the "Do I Know This Already?" quiz is to help you decide what parts of this chapter to use. If you already intend to read the entire chapter, you do not necessarily need to answer these questions now.

This 16-question quiz helps you determine how to spend your limited study time. The quiz is sectioned into four smaller four-question "quizlets," which correspond to four major topics in the chapter. Figure 3-1 outlines suggestions on how to spend your time in this chapter. Use Table 3-1 to record your scores.

1 If given a Class C address with the requirement to accommodate 14 subnets and 10 hosts on each subnet, what subnet mask would you use?

2 List the range of hosts available on the 136.122.10.192/28 subnet.

3 Convert the subnet address 56.98.5.0/24 to binary notation, and state the class to which it belongs.

4 Write out the decimal notation of the following subnet mask presented in this binary notation:

11111111.11111111.11111111.11111000

5 What does VLSM stand for?

6 The Class B network address of 133.222.0.0 has been given a mask of 255.255.255.0. The subnets, 133.222.8.0, 133.222.9.0, 133.222.10.0, 133.222.11.0, 133.222.12.0, 133.222.13.0, and 133.222.14.0 need to be summarized using VLSM. Give the subnet and new mask to achieve this summarization.

7 Is 201.111.16.0/20 a valid subnet mask?

8 Which routing protocols support VLSM?

9 Briefly define route summarization.

10 What sort of design scheme does route summarization require?

11 In route summarization, where is the subnet mask moved?

12 How does summarization allow for smaller routing tables?

13 Identify two private addresses defined in RFC 1918.

14 What is a discontiguous network?

15 What does CIDR stand for?

16 Which RFC is responsible for first describing the use of subnet masking?

The answers to this quiz are found in Appendix A, "Answers to Quiz Questions." The suggested choices for your next step are as follows:

• 2 or less on any quizlet—Review the appropriate sections of the "Foundation Topics" portion of this chapter, based on Table 3-1. Then move on to the "Foundation Summary" section, the "Q&A" section, and the "Scenarios" at the end of the chapter.

• 8 or less overall score—Read the entire chapter. This includes the "Foundation Topics" and "Foundation Summary" sections, the "Q&A" section, and the "Scenarios" at the end of the chapter.

• 9 to 12 overall score—Begin with the "Foundation Summary" section, and then go to the "Q&A" section and the "Scenarios" at the end of the chapter. If you have trouble with these exercises, read the appropriate sections in "Foundation Topics."

• 13 or more overall score—If you want more review on these topics, skip to the "Foundation Summary" section, and then go to the "Q&A" section and the "Scenarios" at the end of the chapter. Otherwise, move to the next chapter.
